HYDROCARBON-BURNER.

Patent No. 742,777, dated October 27, 1903.

(No model.)

To tZZ'wv/om, it 17m/y concern.-

Beit known that I, OSCAR FALKENWALDE, residing in the city of Baltimoreand State of Maryland, have invented certain new and useful Improvementsin Hydrocarbon-Burners, of which the following is a specification.

My invention, which in its general nature relates to improvements inhydrocarbon or gaseous-fuel burners,- is more especially designed foruse in connection with that type of burners now utilized for domesticpurposes in cooking-ranges and heating-stoves and in which ordinarykerosene-oil is the fuel used.

In the practical application of the type of coal-oil burners referred toit has been found that the decomposition of the gaseous vapor of thecoal-oil is more or less incomplete, and by reason thereof considerabledifficulty is found to obtain the desired heating-flame quality of theburners. Furthermore, the incomplete combustion of the oil causes a toorapid consumption of the fuel and the consequent waste of heat by reasonof an improper mixture of oxygen with the gaseous vapor and also thecarbonizing of the burner and the stove with incrustations or deposits,and particularly creates a disagreeable blowing noise.

The above and other objections, hereinafter referred to, I seek toovercome by my presentinvention,which generically comprehends a slow ordrip feeding means for conveying water into a discharging-nozzlesupported outside the hot zone of the burner, whereby to but partlyconvert the water into a moist vapor and for discharging the water in adirection crossing through beside or below the now of the gaseous-vapordischarge from the burner needle-valve or ejector to intermix with thesaid gaseous vapor.

In its vmore subordinate features my present invention embodies certainarrangement and peculiar combination of parts, all of which willhereinafter be fully explained, and specifically pointed out in theappended claims, reference being had to the accompanying drawings, inwhich- Figure 1 is a perspective view of an oilburner equipped with mypresent invention. Fig. 2 is a longitudinal section thereof. Fig.

.of oil-burner which is 3 is a View of my water-dripping attachmentseparated from the burner.

Y In the drawings I have illustrated my pres- Y ent invention as appliedto the special form fully disclosed in and forms the subject-matter ofmy copending application, Serial No. 122,891, and while my presentimprovements are especially designed for use with the said form ofburner I desire it understood that the same in its generic nature isarranged to be used in connection with any other form of oil-burner inwhich the gaseous fuel is ejected into a retort or combustion-chamber.

Y The burner shown comprises a body or casting 1, having a series oftransversely-arranged dues b, that extend entirely across the casting 1,and said iiues b are bisected by a central longitudinal bore or flue a,which extends from the straight end :r of the casting 1 to the taperedend 1c, as clearly shown in Fig. 2, and at the tapered end the bore a isforked and extends divergingly outward to form two oppositely-extendeddischarges ct a.

c c designate a series of air-fines that extend through the bottom ofthe retort and communicate with the iues b, ando is a smaller air-fluethat joins with the central flue or bore a.

2 designates a supporting-base having side and end iianges and providedwith a series of longitudinal pockets to receive an absorb- 'ent body 3,it also having a series of air-slits 2X, which extend the length of thesaid base and through which air is fed under the retort, the latterbeing supported sufficiently above the slits 2 to permit of a propercirculation of air under the retort and in the air-iiues c c. At one endthe base 2 is extended, as at 2a, and on the said extension is mountedan absorbent 2", which is disposed directly under the needle-valve orfuel-ejector g2 to collect the drippings therefrom.

F designates a feed-pipe which connects with the source of oil-supply,and the said pipe joins with an inside asbestos-covered generator-pipeG, that extends up in front of the tapered end of the casting 1 betweenthe fines u. a and connects at the upper end with a horizontal sectionG', supported overthe top IOO of the casting 1,but not in direct contacttherewith. At the rear end generator-pipe sectionG has a pendent memberg, which ter, minates in a Valve-chamber g to receive the needle-valveor ejector devices 92,01? any wellknown construction charge the tluid orvaporized fuel into the bore or main Hue of the casting 1.

In the form of burner as described in operation the dames practicallysurround the body of the casting land pass upwardly over the portion Gof the generator G. Having generally outlined the construction and operation of the burner, I shall now proceed to describe the essentialfeatures of my present invention.

l0 designates an ordinary-shaped waterholding tank or reservoirsupported inany desired manner outside of the range or heating-stove andat such a place where it can be conveniently filled with Water. Asshown, the tank 10 has a feed or offtake pipe l1, having a controllingvalve lla, which is braced on abracket-piece l1b on the pendentpipe-section g, and its end joins with a discharge-nozzle llc, whichfisextended into the bore a and has its outlet of such size as to permitthe Water to escape in drops, and said nozzle I hereinafter term thedrip-nozzle. The nozzle 1lL extends a short distance into the bore a ina plane above the 'flame-discharge from the burner, whereby the Water isdropped in a direction crossing said Hamedischarge or below or on theside of the dame.

The pipe 10 may be of any desired metal and is so supported as to beoutside of the hot zone of the burner, whereby to act as a simple andinexpensive means for conveying water in drops into the burner-flame ata point outside of the retort or body l. mixing with the gaseous vaporfrom the burner acts as a resistance to the vapor, and as it diffuseswithin said vapors it materially aids in loosening the carbon andnitrogen, and, furthermore, by taking up the hydrogen and oxygen a moreperfect decomposition of the oily vapors is effected and the odor of theoil completely overcome. Again, the mixture of the aqueous fluid vvaporscreates a more uniform draft irrespective of the variable flow of thefuel-feed and the disagreeable noises incident in force,

and arranged to dis- The waterv with the gaseous l. In combination witha burner of the class described, said burner including a casting havinga combustion-chamber comprising a central bore and transverse boresintersecting such central bore, and a vapor-ejector discharging into'said central bore, of a watersupply and an otake-pipe therefor,supported outside of the hot z one of the burner, and including adrip-nozzle projecting into the bore of the casting at a point in aplane above the vapor-ejector and at the same end into which the ejectordischarges, whereby to discharge Water in the liquidrstate in dropsdirectly into the combustion-chamber as set forth. i

2. In a hydrocarbon-burner, a combustionchamber, having a centrallongitudinal bore and transverse bores intersecting said central bore, abase, having an extension for said cornbustion-chamber, said base andextension adapted to hold an .absorbent material, a vaporizer mountedover the combustion-chamber and out of contact therewith, avapor-injector connected to said vaporizer and projecting over saidextension to the base, means for injecting Water in thecombustion-chamber in drops as set forth.

3. A hydrocarbon-burner, including a combustion chamber said combustionchamber 'having a longitudinal and transverse bores,

and vertical bores extending from the longitudinal and transverse boresto the bottom of the combustion-chamber,a base for said chamber saidbase adapted to receive absorbent material, a vaporizer arranged abovethe combustion-chamber in alinement with the longitudinal bore of thechamber, an injector connected with the vaporizer and in alinement withthe longitudinal bore from the extension of the base, means forinjecting water into the combustion-chamber at the 'entrant end ofthelongitudinal bore and in advance of the injector, for the purposesdescribed.
